Sydney Sweeney, 29, is reportedly engaged to Scooter Braun, 45. Neither has confirmed it. Within hours the conversation moved off the news and onto a number: sixteen years. This article is not about those two people. It is about what that reaction hides — and about the fact that the data, contrary to public assumption, sit on the other side.
Start where few people expect: divorce. In a Statistics Canada study, Gentleman and Park (1994) combined the 1991 Census with national divorce records. Their model was blunt: divorce rates are lowest when the husband is two to ten years older than the wife — and, more curiously, the model also predicted low rates when the age difference is extremely large. In the same data, divorce was considerably more likely when the wife was the older partner.
So the pattern society is suspicious of is, in the divorce data, the most durable one. Set that beside Brian Pelham in the Journal of Personality and Social Psychology (2021): across 6.4 million American marriages that led to births, plus eight cross-cultural replications involving more than 225,000 mothers, he found that when the husband is somewhat older, infant-survival indicators are better — independent of maternal age.
Now the other side of the scale. Sten Drefahl in Demography (2010), using the complete Danish population register and controlling for education and wealth, looked at longevity and found something different: men with younger wives live longest, while for women both directions carry a cost — older husband or younger — and the lowest cost appeared with a same-age husband.
These findings do not contradict each other, because they measure different things: one measures how long a marriage lasts, the other how long a person lives. Public debate constantly swaps the two. And all three are correlational; none of them says anything about a specific couple.

Why has the partner pool narrowed for a woman of thirty?
Here is the part almost always missing from moral arguments about age gaps: supply. Of American men born between 1990 and 1994, only 20.3 percent had married by age twenty-five. In 2020, 84 percent of adults aged eighteen to twenty-nine were unmarried. Most telling of all: the number of unmarried men aged twenty to thirty-nine rose from 20.7 million in 2000 to 30.4 million in 2025 — a 47 percent jump — while married men in the same band fell from 18.1 to 15.4 million. The average age at first marriage for men reached 30.2 in 2024.
Those numbers describe a simple reality: a woman looking at thirty for a partner to build a family with faces a pool her own age cohort has walked out of. In clinical practice, the pattern I see repeatedly is that men without financial stability do not step forward and keep deferring commitment. [That causal link is my clinical observation, not a research finding.]
The result is two anxieties at once for the same woman: the anxiety of social stigma if she chooses an older, more settled man, and the larger anxiety of ageing past her fertility window if she does not. The belief that a man in his forties is “too late” belongs to two generations ago and does not survive contact with current data — not when the average first marriage for men is already at thirty.
The real variable: other people’s eyes, not the number
Justin Lehmiller and Christopher Agnew showed in Personality and Social Psychology Bulletin (2006) that perceived marginalisation is a significant negative predictor of commitment: people who sense their relationship is not approved of invest less in it. Two years later, in Psychology of Women Quarterly (2008), they turned to age gaps directly and reversed the stereotype: women with younger partners were the most satisfied and most committed group. If an age gap were toxic in itself, that result would be impossible.
So the mechanism of harm is stigma, not the number. And stigma is something you can work on. In the consulting room, what separates the couples who survive that pressure is usually a shared narrative: both partners have the same answer to “why are we together,” and they give it the same way outside the house — rather than one explaining while the other apologises.
A therapist’s work is not only treatment; it is also making room for a healthier public conversation. When the arrangement the data identify as the most durable form of marriage gets suffocated under public judgement, it is real people who pay for it.

There is no scientific threshold. In the Canadian data the lowest divorce rates appeared at a two-to-ten-year gap with the husband older. The ten- or fifteen-year line repeated in public debate has no research basis.
Do large age gaps mean more divorce?
The data do not support that simple conclusion. In the Gentleman and Park model, divorce rates were low both at gaps of two to ten years and at very large gaps. What is clearer is that perceived social marginalisation reduces commitment.
Why are more women choosing older, more established men?
Part of it is structural. The number of unmarried American men aged twenty to thirty-nine has grown 47 percent while married men in that band have declined. When same-age peers commit later, the selection pool shifts upward.
If I am in one of these relationships, what actually helps?
Three things matter more than the number: alignment on life stage (children, retirement, relocation), an explicit agreement about who will care for whom later, and a shared narrative both partners give the same way outside the house.
Conclusion
Three studies measured three different things and none of them produces a simple picture: the Canadian divorce data identified the conventional slightly-older-husband arrangement as the most durable, the Danish register found a longevity cost for the woman, and Lehmiller and Agnew showed that much of the damage comes from the outside gaze rather than the gap itself.
What makes the difference in practice is not age: it is alignment on life stage, candour about the future, and the capacity to stand under public judgement. Those can be built; a date of birth cannot. Perhaps it is time to pull the conversation about this choice out from under the shadow of stigma.
